Question

Calculate The equation of your best fit line is y = 0.565x – 0.056. Use that equation to calculate how high the line will be when x = 100.

a. 55.69
b. 57.12
c. 56.94
d. 58.23

Answer 1

The height of the best-fit line y = 0.565x - 0.056 at x = 100 is 56.444, which rounds to 56.44, closest to option c. 56.94.

Step-by-step explanation:

To calculate the height of the line when x = 100, we use the given equation of the best-fit line, which is y = 0.565x - 0.056. Plugging the value of x into the equation, we get:

y = 0.565(100) - 0.056

y = 56.5 - 0.056

y = 56.444

The height of the line at x = 100 is 56.444, which can be rounded to two decimal places as 56.44. This means the closest answer from the available options is c. 56.94.
